Capable of running CP/M, the Xerox 820-II and its closely related cousin the 820 were supposed to put Xerox firmly in the personal computer race. Unfortunately, the machines didn't take off and failed to make much impact on the market. The Zilog Z80A CPU ran at 4.0 MHz (compared to the 820's 2.5 MHz) and came with 64 KB of RAM.

What many people don't know is that Xerox invented the GUI, mainly with the mouse. Both Microsoft and Apple saw the prototype in 1974 at Xerox and they 'stole' it. Apple accused MS of stealing it from them, Microsoft said no. Xerox came in the middle of it and said, "HA!" Case closed. Xerox wins...financially.
